when you're so wasted you think it's always 30 minutes past the hour, no matter what the clock says
I woke up at 3 a. m. and thought it was o'clock 30 because I was still drunk.
My friend tried to leave the party at 11, but he said it was o'clock 30 and passed out on the couch.
I tried to text my mom at 2 a. m. but wrote 'it's o'clock 30' and she thought I was in a different time zone.
